random_set_seed() in Fuze

Rxvlism

That’s what I’m asking help with I don’t know how to make it and I wanna understand how to make it lol

random( seed ) line 67 is supposed to be random_set_seed( seed ), but we don’t have random set seed

pianofire

@Rxvlism You could try this one https://mathoverflow.net/questions/29494/pseudo-random-number-generation-algorithms

Rxvlism

Ima have to sit down and try understand this cuz I don’t get it even after reading the code on the page, time to study I guess lol

pianofire

@Rxvlism Yes me too. I will put in a request for a random_set_Seed function but it could be a while (assuming it is accepted)

pianofire

In the meantime you could generate some random results and store them in a file so that you can read them back into an array.

Rxvlism

It is a very useful function that and get_perlin_noise

I will try that 🤔

Lol how would u make it, if u don’t mind me asking lol I’m really stumped

pianofire

@Rxvlism OK try something like this:

maxNumbers = 1000
randomRange = 1000
numberLen = 4
seed = 0
nextRandom = seed

randomNumbers = []

// run this once to store the random number sequence
//saveNumbers()
// read previously saved numbers 
loadNumbers()

clear()
for i = 0 to 10 loop
  printAt(0, i, getRandom(6) + 1)
repeat
update()
sleep(3)

function getRandom(range)
  result = int(randomNumbers[nextRandom] / randomRange * range)
  nextRandom += 1
  if nextRandom == maxNumbers then
    nextRandom = 0
  endif
return result 

function saveNumbers()
  handle = open()
  for i = 0 to maxNumbers loop
    randomNumber = random(randomRange)
    write(handle, padStr(str(randomNumber), numberLen, " "))
  repeat
  close(handle)
return void

function loadNumbers()
  handle = open()
  for i = 0 to maxNumbers loop
    randomNumbers[i] = int(read(handle, numberLen))
  repeat
  close(handle)
return void

function padStr(theStr, padLen, padChar)
  result = theStr
  while len(result) < padLen loop
    result += padChar
  repeat
return result

Rxvlism

I will try it out 😂 honestly I don’t know what im doing at this point so hopefully I learn something from you’re code thanks 🙏🏽

I've had success with repeatable random numbers in the past (not Fuze) with a linear congruential generator https://rosettacode.org/wiki/Linear_congruential_generator

Good luck!

Rxvlism

@jmcdowall thanks I’ll take a look 👀

pianofire

@Rxvlism Sorry missed a line when I re-keyed it you need an array declaration near the top

randomNumbers = []

Rxvlism

@pianofire kk now I need to understand how to implement this into my game. If I post it can u help me lol I’ll credit...

Just need to wrap my head around it

Rxvlism

I think this is what it’s supposed to do

pianofire

@Rxvlism no that doesn't look right!. Did you run the saveNumbers() function the first time that you ran it?

uncomment //saveNumbers() by removing the //. This will save a list of 1000 random numbers to a file. Then comment that line out again so that the next time you run it, it loads the same list of 1000 numbers.
